How does it not have any relevance ?! People were discussing a dyno measuring BHP. Is it not relevant to say a dyno doesn't actually measure BHP but torque ?! :rolleyes: Once again, you're confused. The only temp probe I mentioned was the ambient temp probe. The dyno operator wouldn't place the...

Don't worry about witnesses bud and DO take it through the insurers. If it all goes wrong, you'll then have them on your case and they can pull all sorts of tricks. Just be 100% truthful in your claim report and the insurers will soon see whose fault it was. If Plod attended the scene, I'd...

I think it's all down to the driver. I don't know if anyone remembers but, on 5th Gear many moons ago, when it was a decent programme, they pitted the 172 against a Saxo VTS around a track. Tiff Needell was driving the Saxo and that Butler-Henderson thing was drivng the 172. Needless to say...

I didn't say that it calculates torque anymore accurately than BHP simply, that a rolling road actually measures torque. Not BHP. Please read a bit more carefully next time.:rolleyes: Again, I didn't say it would read differently on any given day. How can they allow for incorrect ambients ?! The...

Plus, a rolling road/dyno actually measures torque, not BHP. The BHP figure is a calculation made using a specific formula. You should only really use dyno's as a tuning tool, to compare different mods on the same car, on the same day and on the same dyno. If the OP compares his figures to...

Get yourself a good die grinder, bull nose tungsten carbide bit (or two), a couple of grinding stones and a coupel or small flap wheels. Just take off and casting marks. You can use the inlet and exhaust manifold gaskets as templates, as to how much metal to remove. Use a permanent marker pen...

Wrong. Modern turbo design is far superior to the old days. Better tolerances and materials are used. You just have to look at modern car service intervals to see this. And the 'T' series Garrett turbos are still used in modern cars. The 'GT' series turbos are not used, in general on...

Have you tried Angel Tuning ? My other half emailed them about remapping her R27 and they quoted around £350. That's for them to come to you and treat the car to a bespoke remap, not one of the lesser, generic 'Group N' reflashes that most other 'tuners' offer. Obviously, this is performed...

There seems to be a lot of misinformation/hearsay in this thread. I hope the following helps the OP make an informed decision. 1. Blow off valves (BOV's) and dump valves are the same thing. They're just the different names different countries give them. 2. The R26 will come with a...

Thats exactly right. I personally have a Blitz SUS kit on my car. I know from experience the filtration is far from the best but, the flow it gives is second to none. I'm personally willing to risk it but, I still fancy trying a large K&N or Green cone, for the better filtration, and not greatly...

Cotton filters both flow better and filter more particulates than foam filters. It's very difficult to get the density of a foam filter to flow well and filter out particulates well. So, they compromise and have above average flow and average filtration properties. This article isn't ideal...

Just to add to the above, the 'coolant' isn't just there for it's anti freeze properties, it's also there to stop the car overheating in the summer months. It will also lubricate the bearings in your water pump.

Technically, the pleated cotton gauze filters, like the K&N and Green are the best both in terms of flow and filtration. If you can get a Green 'Group N' element for your model, the have even better flow characteristics than the 'normal' Green filters and K&N filters as, they have 2 layers of...

If you like them bud, that's the only thing that matters. ;)

Thanks mate.

Halogen bulbs are around the 2300k colour temp. Almost all OEM HID (xenon) bulbs are 4300k which, is the equivalent to day light. These have the highest light output, measured in lumens of any colour temperature bulb. Around 3 times as much as the halogen equivalent. If they look to have a...

Did you use any facia adapters with the Becker ? I've just fitted a Pioneer unit to the other halfs R27 and it has unsightly, 1cm gaps on the left and right side that the Pioneer surround doesn't cover. I can't find any facia adapters for the Mk3 Clio's either. Paul

You don't need much unburnt fuel to give you bore wash. Petrol is an extremely effective degreaser. ;)

If you're old pads have plenty of life left in them, then don't bother renewing them. If you buy any decent aftermarket discs from a reputable manufacturer, they'll recommend 'bedding' the new discs in with old pads. This will also mean the brakes become fully effective more quickly as, you're...

That would reduce power and probably give you 'bore wash'. So, you'll need a new engine in no time. Avoid anything like these. The 'tuners' charge you £300 for a reason. It's not cheap to hack an ECU and gain the expertise to then map it to any decent level. And, you'd need a lot of work to...

You need to go and watch the panel, to see if you can live with it. If you can take some of your equipment to plug into it, even better. It's all very well someone saying this particular panel is good but, they don't have your eyes so, you may not agree with them, when you see it. For a...

As above, I agree to a point. As you've said, "any chimp can drive fast in a straight line" but, they need to get the launch right, to win the race at Santa Pod. This can be quite difficult. The track day would definitely be more interesting though. :evil:

Ah, that would explain everything.

And what's that supposed to mean ? If you have something to say to me, say it. Don't flatter yourself bub.... I don't have any opinion on you. But, if you need the reassurance, take it where you can get it. Also, I see all these performance figures you keep throwing in for the M3 or 'your' CSL...

That's "always one, isn't there" old bean. ;)

I'm afraid it doesn't old chum. Although I can understand where you're coming from, if you max out each gear, in any car, you'll be into the zone of most torque on the up shift so, the turbo car making more torque lower down the ropm range, is irrelevant. The same can be said for power, once...

And here is my case in point ! Firstly, in what circles is the E30 M3 talked about as the greatest car ever made ? A very small minded one I'd expect. Secondly, "charver wagon" ??????? Thirdly, I'd agree, the M3 is a drivers car. Whether it is set up by "professional engineers" or, if...

From your example, there are too many variables to give even an educated guess. There is just too much information missing. Do they both have the same displacment engines ? Are the bore and stroke of the engines the same ? Are the gearboxes identical ? What transmission layout does each car...

It's always the same. When someone with a <£13k car says they can (insert whatever it can do better/faster/quicker here) than someone who's spent >£40k on their car, egos and pride take over. Simple physics speak for themselves. The '309' bhp clio will out drag the M3, E30, E36 or E46...

To answer your title question, the K&N. Technically, foam filters are inferior, both in terms of filtration and flow, when compared to pleated cotton air filters.
